LongPredicate
public
interface
LongPredicate
| java.util.function.LongPredicate
|
Represents a predicate (boolean-valued function) of one long-valued
argument. This is the long-consuming primitive type specialization of
Predicate.
This is a functional interface
whose functional method is test(long).

Public methods
and
public LongPredicate and (LongPredicate other)
Returns a composed predicate that represents a short-circuiting logical
AND of this predicate and another. When evaluating the composed
predicate, if this predicate is false, then the other
predicate is not evaluated.
Any exceptions thrown during evaluation of either predicate are relayed
to the caller; if evaluation of this predicate throws an exception, the
other predicate will not be evaluated.
| Parameters |
|---|
other |
LongPredicate: a predicate that will be logically-ANDed with this
predicate |
| Returns |
|---|
LongPredicate |
a composed predicate that represents the short-circuiting logical
AND of this predicate and the other predicate |
negate
public LongPredicate negate ()
Returns a predicate that represents the logical negation of this
predicate.
| Returns |
|---|
LongPredicate |
a predicate that represents the logical negation of this
predicate |
or
public LongPredicate or (LongPredicate other)
Returns a composed predicate that represents a short-circuiting logical
OR of this predicate and another. When evaluating the composed
predicate, if this predicate is true, then the other
predicate is not evaluated.
Any exceptions thrown during evaluation of either predicate are relayed
to the caller; if evaluation of this predicate throws an exception, the
other predicate will not be evaluated.
| Parameters |
|---|
other |
LongPredicate: a predicate that will be logically-ORed with this
predicate |
| Returns |
|---|
LongPredicate |
a composed predicate that represents the short-circuiting logical
OR of this predicate and the other predicate |
test
public abstract boolean test (long value)
Evaluates this predicate on the given argument.
| Parameters |
|---|
value |
long: the input argument |
| Returns |
|---|
boolean |
true if the input argument matches the predicate,
otherwise false |
